Only one assignor can be your primary assignor. If your league requires you to submit a Background Check in order to be assigned to a game, you must set your primary assignor to that which is registered with the league requiring the RM report in order to have the the Risk Management system active. Once you have submitted your RM report, you can change your Primary assignor back to whoever you want.

To set your primary assignor, login to your account and click on REFEREE ASSIGNORS in the blue menu bar. Then click the MAKE PRIMARY button next to the assignor you want as primary.
